Soaringmeteo - Meteorology for soaring pilots


From soarGFS to soarV2

The association Club Soaringmeteo intends to replace soarGFS with soarV2 in 2024. We would like to invite you to use soarV2 instead of soarGFS and let us know any concern you may have. This page explains the motivation behind this decision, and describes the differences between both tools. A more detailed documentation of soarV2 is available online by clicking to the “?” at the bottom right of the page soarV2.

Why replace soarGFS?

With about 100,000 visits per year, soarGFS is a tool that is beneficial to thousands of soaring pilots. Why do we want to change something that works?

As it is explained in the page Support Soaringmeteo, soarGFS is the creation of the passionate, self-taught pilot Jean Oberson. Although soarGFS was developed more than 10 years ago, it is still very useful to soaring pilots. Similarly, soarWRF is used by a growing number of visitors. This is impressive, congratulations to Jean Oberson!

The team of Soaringmeteo volunteers would like to improve further the tools soarGFS and soarWRF: decrease the CPU usage, simplify the user experience, expand the areas covered by the forecasts, reduce the maintenance costs, etc. Unfortunately, maintaining and evolving the software written 10 years ago is hard. Therefore, we decided to rewrite it from scratch. This will allow us to perform the desired improvements more easily while decreasing the risk of introducing bugs and without having to scale up our server infrastructure.

SoarV2 is an open source software, and your contributions are welcome!

Main benefits of soarV2

The main benefits of soarV2 compared to soarGFS are the following:

Default view

By default, the main view soarV2 is similar to the “aerological map” of soarGFS:

In both cases, the color of each point of the map shows the thermal soaring conditions (ThQ in soarGFS, XC flying potential in soarV2). The main differences are the following:


In soarV2, when you click to a location on the map a tooltip shows additional information as well as a button to display a meteogram for this location.

In both cases, the meteograms show the forecast for the next days at the selected location. Overall, both tools show similar information (thermal quality, cloud cover, boundary layer depth, wind speed and direction at various elevation levels, atmospheric pressure, rainfalls, etc.), but the layout is a bit different. The main differences are the following:

Additionally, soarV2 shows the convective updraft velocity (below the XC potential, on the line that starts with “m/s”).
